Any computer with a Duel Layer DVD will Copy a Super CD+G Disc with Roxio. A Disc Duplication.
You can play Super CD+G's on any computer with a Duel Layer DVD. Just let the autorun go when the disc is put in your computer. The discs come with their own player program.
I do my shows with copies of all my disc, including the Super CD+G's. Took me cracking one disc, and scratching another, to learn to keep my originals at home, and only copy them, never play them.
As far as ripping a Super CD+G. Super CD+G is proprietary to CAVS. Only CAVS can read these disc, except for computers. CAVS sells a software for like $30 on their website.
